Real random numbers? Any way to seed this?

[voidflux]

Hello everyone!!

I'm making a poker game, and I need a way to make the dealing randomized, Right now I have a [4][13] array of card objects, and my get function is the following:

I can't have the random numbers be anyting other than
0 to 3 for the columns and 0 to 12 for the rows, because anyhting else will be out of range.



public void getCard(int howMany)
{
Random r = new Random();


while(howMany != 0)
{
int col = r.nextInt(4);
int row = r.nextInt(13);

if (theDeck[col][row].inDeck) {
theDeck[col][row].inDeck = false; //take the card out of the deck
System.out.print(theDeck[col][row].faceType +
theDeck[col][row].cardValue + " ");
--howMany;
}
else
continue;
}
System.out.println();
}


Is there anyway to make this more random?


Thanks!

You can seed either by passing in a long value to the Random constructor or by calling setSeed(long seed).

Thanks, I ran my program about 10 times and it gives me random different random numbers each time, so i'm just not going to mess with the seed. :bigyello:
